摘要 |
Process for the production and extraction of polysaccharides from a porphyridium cruentum culture and apparatus for performing the process. This production and extraction process comprises a stage of concentrating the polysaccharides consisting of leaving the culture medium (1) in a photoreactor (22) exposed to sunlight under stagnant conditions and at ambient temperature, leading to the formation of a polysaccharide-rich cream (23) and recovering said cream by skimming, a stage (24) of heating the concentrate obtained at a temperature between 60 DEG and 100 DEG C., a stage of separating the solid and liquid phases formed (26), a stage (30) of precipitating the polysaccharides contained in the liquid phase and a stage (16) of drying the precipitate obtained. |
